在SDL中显示GBK点阵汉字
时间：2007-02-17 来源：PHP爱好者
大家注意到没有，RA2的中文版本使用的是GBK点阵字库，这样做有一个好处：不管玩家是用的简体还是繁体都能识别显示的文字。
GBK的意思大概是“国家标准汉字扩展字符集”吧，记不清了。但它的确是个好东东，比GB2312、BIG5什么的强多了。因为它包括GB2312、GBK的所有字符而且还补充了很多字，另外，还包括日文、朝鲜文以及大量的符号字符。
我在UCDOS for win版本里面找到了GBK的点阵字库（HZK12.GBK、HZK14.GBK、HZK16.GBK）。分析了一下，知道了结构。这里是我写的一个演示程序，程序编译需要有sdl库。遵循“惯例”，按F4切换全屏/窗口状态，Esc退出。程序把标准输出和标准错误重定向到"stdout.txt"和"stderr.txt"中。
